WINDOW LOCKL Application filed January-14, 1918.-

' To all whom-it may concern:

Be it. known that I, EMORY S.- ,ENsIGN, a citizen of the United States, residing at East Orange, in the vcounty of Essex and State of New Jersey, have invented a new and useful WVindow-Lock, of whichthe-fol lowing is a specification. I a

This invention relates to window locks and is in the nature of an improvement on my U. S. application'No.152,4t20,filed March 3, 1917, where I show an elasticxconnection between sash and frame:

The object of this invention istoshow improved means for connecting the ends of the elastic member, particularly such means as will permit entire removal of said member without dismounting the fixtures that hold it in position for use. Other features of novelty will appear in the following description. 7

In the drawings which accompany and form part of this specification,

Figure 1 is a partial View of a double window sash with its frame, showing two of my locks, one for each sash.

Fig. 2 is an enlarged view of the lower lock shown in Fig. 1.

Fig. 3 is a view of Fig. 2, taken at right angles thereto.

Fig. 1 is an under plan View, sectioned on line 1-1 of Fig. 2.

The lower and upper sashes are marked A and B respectively, and the casing in general is designated by the letter C.

Referring to Figs. 2, 3 and 4, I attach firmly to casing C, as by screws 2, a socketpiece 1 formed of bent sheet metal and partially embedded in the casing, as seen in Figs. 2 and 4:. Communication to socket 3 of socket-piece 1 is obtained by a slot 4: adapted to receive the bent tongue 5 of spring 6 in such a manner that spring 6, when positioned for use, must be turned through an arc of, say, 90 degrees from entering position, so that tongue 5 will lie across slot 4. and prevent the detachment of spring 6. Thus, when positioned for use, spring 6 has, preferably, a limited, free, vertical and bodily movement with relation to socket-piece 1.

The opposite end of spring 6 is looped in a manner somewhat similar to that shown in my previous application referred to, but I here end the loop 7 at 8, somewhat above the coiled portion of spring 6. For detach- I Specification of Letters Patent.

Serial No. 211,893;

able engagement of end-8,1 provide a plate 9' firmly attachedto sash A by screws 10-and having a bent ear 11, somewhat rounded and perforated at 12 to 'slidably receive one leg of loop'7. a

By inspection of the drawings, it will be seen that slot 4-bears' such a relation to the positions of end 8 and ear 11that when spring 6 is lifted as far as slot lwill permit, it must beslightlyextended against its elasticity to permit end 8 to be detached from ear 11. My reason for preferring thisform of construction is two foldQ-fir'st, that 1 careless handling of the spring when manipulating the windowmay not accidentally-detach end-8 "from car 11 and, second, that anyone tampering with the look from the outside would have to extend the spring before'it could be released. In practlce, this extension would amount to no more than a stiffening of the lost motion inherent in mechanical movements of this character.

Either method of detachment, viz.that of elongating slot l sufficiently to freely permit end 8 to leave ear 11, or that of entirely relying on the extension of the coils of spring 6 to permit this disengagement, might be properly effective alone and I do not limit myself to the combined use of both methods. If it should be desirable that the latter method only be employed, socket-piece 1 would be secured to the casing in a position rotated 90 degrees from that shown, and tongue 5 would be twisted so that, in use, it would still lie across slot 4:; or, preferably, tongue 5 would be so formed as to lie at an angle of 45 degrees across slot 4, when in use, and thus no change need be made in tongue 5 when rotating socket-piece 1 through the above 90 degrees.

After freeing end 8, as above, spring 6 may be allowed to hang from socket-piece 1 in inverted position (see dotted line in Fig. 1) and thus the liability of mis-laying spring 6 is avoided; or, if preferred, tongue 5 may be removed from socket-piece 1 and spring 6 be laid away until it is again desired to lock the window.

Socket-piece 1 and plate 9 are fixtures, but very inconspicuous ones, and will not interfere with the ordinary manipulation of the window, when cleaning or repairing of same is required. My spring, therefore, may be either partially or wholly detached, when Copies, of this patent may-be obtained for fiv e cents each, by addressing the v Washington, D. 0.?-

freely without interference from the lock on sash B, as said lock occupies only the space of parting bead'D, between the sashes, and

clearance can be cut in the weather strips that; ordinarily bridge this space.

If desired, plate 9 may be embedded flush in the wood and socket-piece 1 may also'be entirely instead of partially embedded in strip E. In this way, ear-'11 would form the only fixed projection, and socket-piece 1 would be directly secured to casing C, instead of strip E as shown, so that the latter could be moved'or removed without inter fering with the lock. 1

I do not limit myself tothe precise construction shown. 'What I claim is: J I

The combination of a window casing and a window operati ely mounted therein ,.with a flexible window lock comprising a closeriorly'mounting said spring in a Vertical position against said casing, said. means com- :vided with'aslotcommunicating with the coiled, spiral spring; and'means. for extesocket, said slot being adapted for the pas- I sage therethrough of said tongue when in register therewith, a second fixture, means for removably securing the opposlte end of sald sprlng to-sald second fixture, and means for rigidly attaching said fixtures to said casing and Window, one toeach, with said slot vertically disposed. Y

In testimony whereof, I hereto affix my signature, in the presence of twowitnesses.
